From Bushwalk Australia
Hill or ridge formed from material deposited by a glacier.
A 'terminal moraine' is formed at the tail end of a glacier where the rocks and debris of glacial erosion are released from the ice as it melts.
A 'lateral moraine' is formed along the sides of a glacier.
The most well known moraines in Tasmanian bushwalking are the lateral moraines along the north eastern side of the Western Arthur range with each being named after letters of the Greek alphabet (starting with Alpha Moraine), but often just being referred to by their English letter equivalent (starting with Moraine 'A').
